Jeffers Petroglyphs Historic Site is about 3 mi. w. on CR 17 to CR 2, then about 1 mi. s. to 27160 CR 2. Set amid 160 acres of tall-grass prairie are quartzite outcroppings embellished with petroglyphs, some thought to be at least 7,000 years old. The earliest of the rock carvings include scenes of buffalo hunts and other animal and human images. The petroglyphs are visible from several boardwalks and a roped path along a quarter-mile trail; the best viewing time is at dusk. A visitor center has exhibits about the prairie environment and Native American culture.
